Application filed June 19, 1924. Serial No. 720,913.

Another object is to make a hay pressli? having an improved tucker for turning downthe ragged edge at the upper side ot' the last charge of hay in a bale.

Another object is to make ahay press having wire threaders and adapted to make 2l bales of hay with their widest dimensions horizontal so as to make it possible to make a larger entrance for the loose hay.

@ther objects and advantages will appear 'from the drawings and specification.

The drawings illustrate a hay press having vertical threaders and a tucker in accordance with the principles of the invention.

Fig.` 1l is a View analogous to Figs. 8, 9 and l0 and showing theoperation ot Inoving the tucker out of the way of the needle,

this being a step' behind the o eration shown in Fig. 9 and a step ahead ot the operation shown in Fig. 10.

rThe details of construction and operation shown in the drawings are as follows:

rlhe hay press is constructed so that the compression chamber l is'wider horizontally thanit is vertically, thereby making it pos sible to use a large rfeed hopper 2 and provide a large inlet or throat 3 for the introduction of loose hay so as to speed up the operation ot making bales, and when the` bales are made with their widest dimensions horizontally, it is necessary `to thread the wires around the bale in Vertical planes.

In order to turn the ragged edge 7 oi the last charge 8 ot a bale 9, in the making, downwardly and make a good finish., a tucker l0 is mounted upon a pivot 1l at the bottom ot the throat 3. rlhe tucker 10 may be about one-third as wide as the vertical thickness of a. bale and the pivot ll is at the forward edge, and the tucker is adapted to swing upwardly to a horizontal position while the bale is being formed, and then after a charge of hay 8 has been pressed against the rear end of the bale, the tucker is operated to swing downwardly, thereby pressing the ragged edge 7 downwardly and when it comes to the last charge in a bale then the next operation of the plunger l2 will press the ragged edge 7 against the charge 8 and make a round upper edge on the charge. Then the plunger l2 recedes and the wires are threaded upwardly between the charge 8 and the receded plunger l2 and during the threading operation the tucker 10 is swung downwardly and haeltwardly out. of the way of the needle carry ing the wires,

The details of the needle construction 13 `for threading the wires 4, 5 and 6 around Vguide roller 22 and upwardly through a slot y24 formed in the bottom of the coni.- pression chamber 1 and through a slot formed in the top of the compression chainber innnediately behind the hopper 2. The guide roller 22V has grooves in which the wires run. A handle 19 isixed in the arm 19 for manually operating` the slack producing arms 13 and 19 carrying the roller 22.

Needle Vcarrying arms 26 and 27 are mounted upon the bolts 2O and 21 and curved needles 23 and 29 are rigidly connected to the swinging ends of the needle arms 26 and 27 and are suitably braced. crosswise, and a guide roller 30 connects the swinging ends of the arms 23 and 29 and has wide flaring grooves 31 in which the wires 4, 5 and 6 run. The radius of swing of the roller 30 is less than that of the roller 22 so that when the roller 22 swings backwardly to produce a slack, as in Fig. 9, the roller 22 will pass outside of the needle arms 23 and 29 and the wires will engage in the grooves of the roller 30, thereby pro' ducing slack in the wires to double the extent of the distance to which the roller 22 passes beyond the roller 30,

rl`he bull wheel shaft 32 has a crank fixed upon one end and a crank 34 lined upon the other end, the cranks 33 and 34 being at angles of 90o relative to each other. A connecting rod 35 is connected to the cranl: and the free' end of the connecting rod 35 rides continually upon a pin 36 fixed inthe arm 27. A latch is connected to the rod 35 by a pivot 38 and has a handle 39 for manual operation. A linger 4U eittends from the opposite end of the latch 3^( from the handle 39 and rests upon a spring 41 secured to the rod 35 by a pin 42. A dog 43 projects downwardly from the latch 37 immediately' behind the finger 40 and is adapted to engage the pin 36 lined in the arm 2T. Normally the spring 41 holds the latch dog 43 out of engagement with the pin 3G. lhen the needle is in the position show-n in -Figs3 and v8 and it is desired to thread the wires around the finished end of a bale, t-he operator raises the handle 39 and continued operation of the red will cause the latch dog` 43 to engage the pin 33 and swing the. needle arms 23 and 29 carrying the roller 30 upwardly between the bale 9 and the withdrawn plunger 12, as shown in F ig. l0.

A stop 45 is secured to the arm 27 and bent outwardly and extends upwardly to engage the rod 35 to lift the latch 43 and release the needle arms 23 and 29, shown in Fig. 7. 1an arm 46 extends from the inner end of the arm 25, and a second arni 4'? .extends from the outer end of the arm 25, the arms 46 and 47 being connected at their outer ends. A. connecting' rod 4 3 connected to the crank 34 and has a slot r9 in which a pin 5() operates to a limited ei;- tent, the pin being fixed to the arin 26 so that as the bull wheel shaft 32 rotates to operate the crank 34, the connecting rod 48 will slide on the pin 50 in the slot 49 and as the crank 34 moves bacliwardly the pin 50 will roach the forward end of the slot 49, and continued operation will swing the arms 25 and 27 backwardly, thus withdrawing the needle a ms 23 and 29 to their normal positions, as shown in 3.

rllhus it will be seen that when a bale is to Y be finished the operator moves the handle 39 upwardly, thus connecting the rod 35 to the arm 27 and threading the wires upward ly, and immediately upon the nent quarter turn of the bull wheel shaft the crank will operate the rod 48 to withdraw the needle arins 23 and 29, and the needle arms remain in their withdrawn 'positions until the operator again raises the handle 39. fr handle 44 is fixed on the pin 36 for manual manipulation of the needle arms 23 and 29.

A connecting rod 51 is attached to the meeting ends of the arms 46 and 47 and has a'slot 52. A crank 53 is fixed to the pivot 11 and has a pin 54 operating in the slot 52. When the tucker 10 is in horizontal posi tion, as when the bale is being produced, the pin 54 operates freely in the slot 52 to allow the tuclrer to vibrate as the hay passes under it. The rod 51 serves to pull the tueler 10 downwardly and swing it forwardly far enough to allow the needle arms 23 and 29 to pass upwardly without colliding with the tucker 10. A second crank 55 is lined to the pivot 11 and extends downwardly, and a cord 56 is connected to the crank 55 and to the connecting` rod 48.

At each revolution of the bull wheel shaft 32 the Ycord 56 will be pulled to swing the tucker 10 downwardly, thereby folding the ragged edge of each charge of the bale downwardly so as to make round upper edges ont' the charges. During this operation the pin 54 will slide in the slot 52. A plurality of dogs 57 are mounted upon pivots 58 in bear ings extending forwardly from the supporting bar 59 and the points of the ldogs raise lll( lll

to allow the plunger and hay to pass, and then the points yfall to'engage the upper edge of the last charge of hay 8 so as to hold the charges upright. Stops 60 hold the dogs 57 from swinging forwardly under the tension of the rebound of the hay. v Y

l/vire cutters 61 are mounted upon the supporting bar 59, there being a complete wire cutter for each wire 4, and 6, and the wire cutters are connected together by a handle 62 for simultaneous operation. Each wire cutter 61 has a rigid cutting jaw 68 mounted upon the bar 59 and a swinging cutting jaw 64 pivotally mounted relative to the jaw 63 on a hinge pin 65. in arm 66 extends from the pivoted jaw 64 and is 1pivotally connected to the bar 67 carrying the handle 62. A recess 68 is formed in the lower face of a rigid jaw 69 and the rigid wire holding jaw 69 is mounted above the jaw 64, which extends under the recess 68, so that when a wire carried upwardly by the roller past the open ends of the jaws 68 and 64 passes between the jaws and the handle 62 is operated, the wire is cut by the jaws 68 and 64 to leave the end 76 free, and the end 7l severed from the end 7 9 is bent under the jaw 69 in the ren cess 68 and ultimately this end 71 is held while the new bale is being made, and when the bale has been finished the end 71 is re leased by pushing on the handle 62 and becomes the end 72 and the ends 70 and 72 are twisted together in any of the well known ways to form a bale tie for the finished bale.

The wire carried by the roller 30 in the groove 31 passes straight up and straight back, and in order to catch and hold the wire end 71 the inner edge of the jaw 69 has a shoulder 73 extending horizontally and a shoulder 74 extending downwardly and forming one end of the recess 68 so that as the wires tuck under the jaw 69 in the recess 68 and the roller 8O recedes the wire will engage the shoulder 7 3, and the shoulder 74 and the pinch upon the wire in the recess 68 will hold the wire while the next bale is being formed.

The needle arms 28 and 29 are concentric to the axis formed by the bolts 20 and 21 and are connected together by brace rods 75 and 76 and the brace rods 7 5 and 76 form guides against which the wires bear during the threading operation as shown in Fig. 6.

In our constuction of hay press as above described we utilize a compression chamber wider horizontally than vertically and thus utilize a feed hopper which may be made considerably wider .than those making standard bales in accordance with the standard practice of having the bales higher thantheir width. For instance, a standard bale measuring 14 inches in width would be 18 inches in height and 36 inches in length and have the binding wire pass around the bale hori- Zontally, whereas in our construction we makethe same size bale by having the width .18 inches, the height 14 inches and the length 36 inches-with the binding wires passing around the bale vertically. rlherefore we are enabled to feed the hay through the hopper more rapidly in our type of wide press than in the standard type of narrow press.

In baling hay it is the practice to have the length ofthebale twice one of the` other measurements so that the bales can be stacked up properly, breaking joint.

Various changes may be made without departing from the spirit of theinvention as claimed.

We claim:

1. A hay press comprising in combination a compression chamber, a hopper having a throat positioned above the. chamber, a tucker plate pivotally mounted on one side of the throat with the free end of the plate i extending towards the compression chamber, means to swing said tucker plate downwardly to engage the ragged edge of a charge, needle arms adapted to carry a wire vertically at the end of the bale and means operatively connected between the tucker plate and the needle arms adapted to swing the tucler plate downwardly in a vertical direction .t0 allow passage of the needle arms.
